【问题描述】：

我正在使用 Flutter TTS 插件制作一个简单的文本转语音应用程序，并在我的物理 iPhone 和 iPad 上运行它以进行调试。

我尝试用谷歌搜索它，颤振的 github 存储库说我应该运行颤振分析，我这样做了，但它说没有发现任何问题。所以我不确定该怎么做。我认为这是xcode的问题。

这是我的错误：

【问题讨论】：

您是否在 inpo.plist 文件中添加了所需的权限？？
什么意思？

标签： ios xcode flutter

【解决方案1】：

- Platform in ios/podfile you can use platform :ios, '10.0'
- If you are changing platform version in podfile than you have to also change version in AppFrameworkInfo.plist.
- Also change version in Deployment Target and Deployment Info of Runner.

- If not working than you have to try with this below commands using for uninstall and install again pods and Run.

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile
flutter run

【解决方案2】：

这里把版本改成9.0就可以了。

【讨论】：

已经是 9.0。还是不行。
试试这个stackoverflow.com/questions/63973136/…

【解决方案3】：

您需要通过在 xcode 运行器和目标中更改部署目标将其更改为 9 或我认为 10，还需要在 pod 文件中更改它，通过删除 # 取消注释 #platform :ios, '8.0' 并更改字符串到 10.0。你也需要改变这个 post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) 进入这个 post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0' end end end 在你的 pod 文件的末尾

【解决方案4】：

按照以下步骤操作：

转到 ios/Podfile 并取消注释 platform: ios 参数并替换为

平台：ios，'9.0'
在 ios 文件夹结构中运行以下命令

吊舱安装
运行命令flutter upgrade
运行命令flutter run
